About this part
Speedometer Calibrator, fitment-checked
Rough Country 90007 is a plug-in speedometer calibrator for gas-engine Dodge Ram 1500 (2006-2010), Ram 1500 (2011-2017), and Jeep Wrangler (2007-2017) models. It corrects speedometer readings after a larger tire swap, adjusts factory ECM shift points and electronic stability control for the new tire size, reads stored trouble codes such as a check engine light, and can put the vehicle back to stock settings. Gas engines only — it does not work on diesel models.
This speedometer calibrator for the 2006-2010 Dodge Ram 1500, 2011-2017 Ram 1500, and 2007-2017 Jeep Wrangler in both 4WD and RWD covers the trims listed in the fitment section. Plan on 5-10 minutes for the handheld connection. It runs as a standalone tool and will not work alongside a performance programmer, and it is not for sale or use in California. Once programmed, the unit locks to that vehicle until that vehicle is returned to stock, so it serves one truck or Jeep at a time. A downloadable installation guide is available.
